CARTRIDGE AND IMAGE FORMING APPARATUS

摘要

A cartridge includes a first maintaining member and a second maintaining member, each disposed on respective end portions of a charging roller in an axial direction of the charging roller and configured to maintain a position of the charging roller at a first position, and a first moving portion and a second moving portion, each disposed on respective end portions of an image bearing member in an axial direction of the image bearing member and configured to respectively abut on and move the first and second maintaining members according to rotation of the image bearing member so as to move the charging roller from the first position to the second position. When the image bearing member is rotated in which the charging roller is in the first position, the first moving portion abuts on the first maintaining member, and then the second moving portion abuts on the second maintaining member.

主权项

1. A cartridge including an image bearing member and a rotatable charging roller for charging the image bearing member and capable of moving the charging roller from a first position to a second position closer to the image bearing member than the first position, the cartridge comprising:
a first maintaining member and a second maintaining member, each disposed on respective end portions of the charging roller in an axial direction of the charging roller, the first and second maintaining members being configured to maintain a position of the charging roller at the first position; and a first moving portion and a second moving portion, each disposed on respective end portions of the image bearing member in an axial direction of the image bearing member, the first and second moving portions being configured to respectively abut on and move the first maintaining member and the second maintaining member according to a rotation of the image bearing member so as to move the charging roller from the first position to the second position, wherein, in a case where the image bearing member is rotated in a state in which the charging roller is in the first position, the first moving portion abuts on the first maintaining member, and then the second moving portion abuts on the second maintaining member.
